</span>I do not think so - I do not think anything changed since this:<br>

I agree it sounds like a useful thing to have. Not sure how hard it<br>
can be to implement it. Feel free to open an RFE bz.<br></blockquote><div><br></div><div>We are using a disk lease to prevent split brains, AFAIK snapshots are not compatible with disk leases.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Basically, we'll have to:<br>
<br>
1. Make sure everything continues to work sensibly - engine/vdsm do<br>
the right things, ha agent works as expected, etc.<br>
<br>
2. Provide means to start the vm from a snapshot, and/or revert to a<br>
snapshot. This is going to be quite ugly, because it will have to<br>
duplicate in ovirt-hosted-engine-setup/-ha functionality that already<br>
exists in the engine, because at that point the engine is not<br>
available to assist with this.<br>
